IELTS Writing Task 1 question

The diagram below shows how fabric is manufactured from bamboo.

Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

Write at least 150 words.

Student answer (Band 7.0)

The diagram illustrates the process of manufacturing fabric from bamboo, from planting the bamboo to producing the finished material.

Overall, the process consists of several stages, beginning with the cultivation and harvesting of bamboo and ending with the production of fabric. The bamboo is progressively processed into fibres, which are then spun into yarn and woven to produce the finished material.

The process begins with bamboo being planted in spring. In autumn, the bamboo plants are harvested and subsequently cut into strips. These strips are then crushed to produce a liquid pulp, which is filtered to separate the long fibres from the liquid. Finally, the fibres are softened by adding water and amine oxide.

The softened fibres are then spun to produce yarn. The yarn is subsequently woven to make fabric which is the last process of manufacturing fabric from bamboo, which is ultimately used to produce clothing such as shirts and socks.

Task Achievement / Task Response — Band 6.5

The response successfully covers all stages of the bamboo manufacturing process, from planting to the final product. You have clearly identified the main features and provided a logical summary. The overview is effective, as it captures the transformation from raw material to finished fabric. However, to reach a higher band, ensure that you explicitly mention the specific chemical inputs or environmental conditions if they are highlighted in the diagram, as this adds depth. The description of the process is accurate and follows the sequence shown in the visual prompt, demonstrating a good understanding of the task requirements.

Coherence and Cohesion — Band 7.0

The essay is well-organized with a clear introduction, overview, and body paragraphs that follow the chronological order of the process. You have used cohesive devices such as 'subsequently', 'finally', and 'which are then' to link ideas effectively. The progression of information is logical and easy to follow. Paragraphing is used appropriately to separate the initial stages of cultivation from the later industrial processing. To improve further, try to vary your cohesive devices slightly more to avoid repetitive structures, but overall, the flow of the text is smooth and coherent.

Lexical Resource — Band 6.5

You have used a sufficient range of vocabulary relevant to the topic, such as 'cultivation', 'harvested', 'crushed', and 'amine oxide'. This demonstrates an ability to use topic-specific terminology accurately. While the vocabulary is functional and precise, it remains somewhat standard. To achieve a higher score, you could incorporate more sophisticated collocations or synonyms to describe the transformation process, such as 'converted into', 'undergoes', or 'transformed into'. The spelling is accurate throughout, and the word choices are appropriate for an academic report, ensuring clear communication of the technical process.

Grammatical Range and Accuracy — Band 7.0

The response displays a good mix of simple and complex sentence structures. You have used passive voice effectively, which is essential for describing a manufacturing process (e.g., 'bamboo being planted', 'strips are then crushed'). There are very few grammatical errors, and the punctuation is generally correct. The sentences are well-constructed and easy to read. To push into the higher bands, you could experiment with more varied complex sentence structures, such as using participle clauses or more sophisticated relative clauses to combine information more fluidly, though your current control is already quite strong and error-free.
